Fig. 2 is a top view of fig. 1.

Fig. 3 is an enlarged view at K in fig. 1.

The sealing structure comprises an outer cover 1, an inner cover 2, a sealing plate 3, a ventilating pipe orifice 4, a first flange 5, a first groove 6, a cross fixing rib 7, a connecting bolt 8, a cross reinforcing rib 9, a ventilating pipe orifice 10, a sealing plate supporting ring 11, a nut 12, an elastic washer 13 and a handle 14.

Detailed Description

The top sealing structure of the aseptic tank shown in fig. 1-3 comprises an outer cover 1, an inner cover 2 and a closing plate 3.

Wherein, the cover 1 is sleeved on the vent pipe mouth 4 positioned at the top of the sterile tank with an upward opening, and the cover 1 and the vent pipe mouth 4 can be fixed by welding. The inner cover 2 is covered on the air vent pipe mouth 4 with a downward opening. Specifically, 1 bottom surface middle part ring of dustcoat is equipped with

first flange

5, and 5 inboards of first flange are equipped with the first recess 6 around the mouth of pipe 4 of breathing freely, and inner cup 2 corresponds first recess 6 position and is equipped with the second flange, corresponds first flange 5 position and is equipped with the second recess to form joint cooperation relation with dustcoat 1 when inner cup 2 lid closes on mouth of pipe 4 of breathing freely, guarantee the connection effect. In order to further improve the connection reliability, upper portion can also set up the fixed muscle 7 of cross in the mouth of pipe 4 of breathing freely, and the fixed muscle 7 central point of cross puts and is equipped with the screw hole, and inner cup 2 corresponds this screw hole position and is equipped with the trompil, thereby connecting bolt 8 passes the reliability that the downthehole further reinforcing inner cup 2 lid of trompil screw in bolt closed, prevents to jolt the inner cup 2 that probably leads to because of the transportation not hard up, guarantees sealed effect. The lower part still is equipped with cross strengthening rib 9 in the ventilative mouth of pipe 4, and 9 thickness T1 of cross strengthening rib are greater than the fixed muscle 7 thickness T2 of cross to strengthen ventilative mouth of pipe 4's intensity, can effectively support top seal structure. The outer side of the bottom surface of the outer cover 1 is provided with a ventilation pipe interface 10.

As shown in fig. 3, the sealing plate support ring 11 is welded on the inner surface of the top of the outer cover 1, the sealing plate 3 is fixed on the sealing plate support ring 11 through screws, the nut 12 is fixed on the lower surface of the sealing plate support ring 11 through the corresponding screw passing position welding, and the elastic washer 13 is further arranged between the sealing plate 3 and the sealing plate support ring 11, so that the sealing plate 3 can be quickly disassembled and assembled when the inner cover 2 is required to be disassembled.
